Another theme im trying to work out for the pyro, called the psycho pack. It is early in the process, so here is the concepts:
The Freaky Fedora a fedora hat for the pyro reminiscent of freddys
The Teeth Grinder a chainsaw that would replace the axe, very fitting for pyro imo
also is just like an upgraded axe lol i would choose to make the teeth of the saw much bigger, to fit with the name
The Goal Stopper a jason like mask, but instead of those red markings, maybe flames? idk. would be a misc item
The WW1 a world war one type flamethrower (insert all W1 jokes here lol) that is a nice change to the pyros regular flamethrower
